TO ALL WHOM IT MAY CONCERN:

' Be it known that I, Josnrn II. Moons, of the city of Chicago, countyof Cook, and State of Illinois, have invented certain new and usefulimprovements in Ventilators for Railway Cars; and I do hereby declarethat the following is a full, true, clear, and exact descriptionthereof, reference being bad to the accompanying drawings, making a partof this specification, in which- Figure 1 is a top view with a portionof the case removed, and

Figure 2 a vertical section;

Like letters refer to the same pnrts in both figures.

Thenature and object of my invention consist in constructing aventilator for railway cars with a revolving sluift'provided with rodsor points projecting out sufficiently far to dip'into a water-bathlocated at the bottoin of the ventilator, so that a shaft rotated byfans will operate easily in the bath, and throw suficient water to keepa screen or perforated diaphragm moist and-washed; in providing aventilator constructed substantially as shown with a screen ofperforated diaphragm near the shaft, or between it and the opening forthe discharge of the purified air, so that it can be kept moist or dampby the operation of the.rods of the shaft; and in the several newcombinations hereinafter set forth and claimed. v i

To enable others skilled in the art to malre and use my invention, Iwill proceed to describeits construction and operation. I

The 'case A is made of wonder metal, or partly of both, as may bedesired. It is about four and one-half i feet long, and-from two tothree wide, and'about four inches deep at the inner end, andabout'e'ighteen inches deep at the outer end, where the shaft andwind-wheel are located. The bottom of the outer end may be madecylindrical, as shown, or in any other suitable form. This case or boxis made into two compartments by the perforated or gauze plate ordiaphragm E, which may bem'ade straight or curved, shown.' I prefer thechrved form, and also to have it'located so as to be near the sprinklersa 0, attached to the shaft C. It'can, however, be located further backthan is shown. Thebest partition or diaphragm 'will b9 made ofgauselsads with small copper wire. It is attached to the case by'meansof a flanch, b, turned at the ends, apd bolts 0, pro vided with largenuts' or washers, or by any other suitable means. Atthe inner end anopening, F, is made for the passage of the purified air into the car.This may also be covered by sperforated plate, wire gause or netting, orby a simple register. The bottom of the outer.end is made water-tightfor the bath B, which, in win'ter, may be made sulficiently'salt toprevent freezing. Over this bath I place the shaft 0, which is supportedI by standards d, which standards are placed vertically across theopening for the doors at the sides At each epd of the shaft I attach thefans D, which are attached to the shaft by,the arms e, and are set at'such an angle as will cause the shaft to revolve by the action of thecurrents of airwhen introduced from either side ofthe ventilator.Between thesefans I insert, or otherwise attach to the shaft, thesprinlrlers' a a. Theseare arranged spirally, as shown, so. that theirweight will be' evenly balanced upon the shaft. They are made of smallcopper wire, about seven inches in length, and flattened'at the ends, orare made spoon-shaped, if desired. It a suflicient number are attachedthey will not even require flattening; but when flattened I placethem'about' one inch apart. The'dcors G are single doors and are hingedso as to open inwards or towards the-centre of the car; and they restagainst and are held by rests or cstchesplaced on the bottom of the carfor that purpose, and are so held'that tlrey will, from their position,which is a little back of the right angle, act in or to a certain extentas wind-gatherers or directors. Automatic doors, such as weredescribedhy me in a previous application,. may be used.- It is designedby me to place two of these ventilators upon each car, opposite,-ornearly so, to each other, atthc bottom, with the both end outwards, sothat the line of the shaft 0 will correspond with the line of the car,and bring the fans D in a position to be operated by the air-currentsformed by the I ion of the car or train. In operationthe door which,from thedirection of the train, will be the forward door is opened andfastened in position, and a.- rear one closed, when the air will enterthe'ventilator, and, striking or impinging against the fans, will causethe shaft with the sprinklers to revolve rapidly, which will not onlykeep the diaphragm moist-and washed, but will keep the drum of theventilator filled with drops or'particles of water, which, with thediaphragm, purifies the air from the dust and small particles of ashesand cinders. The air, after passing the diaphragm, passes through theventilator, and into the car at F, or at any other convenient point,from whence it is distributed through the cur by aux suitable means, orby a simple register. lIusuully provide the ventilators with cocks orplugs to draw off the bothuhen it lJVcOlllCS foul; Thisrentilator willbe found simple and cheap in its comtruction, nnd effective inaccomplishing the desired object of introducing clear and pure air intorailwaycnrs, and, whenever used in connection with the usual upperventilators, rinilowa, or registers, will cause currents of pure air tocirculate through the cars.

Having tliusfully described my invention, what 1 claim as new, 'mnldesire to secure by Letters Patent, is- 1. The shaft C, when providedwith rude or ilnshcrs a a, uttacheil spirally, as described, incombination with the wind-fans I), located inside of the casing.substantially as and for the purposes deecriboil.

2. The shaft C, [It0\ld6(l with the rode a a and fans D, located andoperating no tlOoCTlbC l in combination with tho dooro G and both 13,substantially asspcc fieil.

3. The perforated diaphragm or partition E, in combination with theshaft 0, provided-with rods-or tlusiiers a a, and water-bath B, thewhole constructed and operating substantially specified.
